Default Amp Bridging Question

This should probably go in the interior/stereo section but I am installing my amp tomorrow morning and want to get this sorted out.

I have been told that my amp is bridgeable, but I honestly don't know how to bridge an amp. I might get blasted for it, but im new to the stereo scene.

Anyways, its a 2 channel phoenix gold amp being hooked up to my sub. I will take pics after the install is done.

My question is: How do I bridge the amp? Is it as follows:

Left channel wire the + and - together then use the + to the sub.
Right channel wire the + and - together then use the - to the sub.

Am I correct? All I want is to blow something.

Thanks guys.

Left channel wire the + and - together then use the + to the sub.
Right channel wire the + and - together then use the - to the sub.
It sounds like you are connecting the positive wire to the negative wire then sending that to the pos on the sub......YOU NEVER CONNECT A + and a -.
First, is your sub a single or dual voice coil?
If SVC:
Wire the two positves together, then the two negatives together and connect them to the positive and negative terminals on the sub, respectively.
If DVC:
Just run one positive on the amp to one positive on the sub, then another, then do the same thing with the two negatives.

BUT, IF IT IS A DVC, you have to make sure your amp can run at the impedance you will be running, so you have to know what impedance your sub is. If it is a four ohm, you are probably fine, the total impedance will be two ohms. If it is a dual two ohm, then you will be running at only one ohm. And if it is a dual one ohm, like a power acoustik or something, then you will be running at only 1/2 of an ohm, which only a select amount of custom amps can do this.

Just compare what your sub says to what your amp can run at. If you still have trouble, post it on here and we can help you more.

Wow... thank god you posted. Some site told me to put the + and - together. I thought it was wrong, but it was an audio website.

Thanks for the post.

A lot of amps (if they are bridgeable) will denote one positive lead (for example from the left channel) and one negative lead (say from the right channel) as bridging posts. Meaning, take the positive from one channel, and the negative for another and hook them to your SVC sub.
